Paired experiment to identify truth and lie indicators in the natural conditions



The aim of this work was to develop an experimental design to study the manifestations and methods of detectingthe indicators of reliability/unreliability of the reported information in the situation with high ecological validity. In this regard, the adaptation of the card game “I Believe, I do not believe”, which can be played by two players, and the maximum points can be obtained in situations where it is possible to outwit the opponent or reveal his cunning, was made. To ensure the possibility of further analysis of manifestations and methods of searching for indicators of reliability/unreliability of the reported information, the interaction of players is carried out by means of video communication, and the video streams themselves are recorded. Additionally, oculomotor activity of players is recorded for further analysis of strategies for searching for signs of truth/lies during the game. The software and hardware complex implementing this game is developed, performing synchronous recording of the game process, communication of players through the video communication system, as well as oculomotor activity of players. The results of pilot study conducted with the use of this complex are presented.
